On the covered Kenmore 111 model bottom-freezer refrigerator, iD Lo or iD Hi means Kenmore's service table lists this code as: ice room temperature sensor failure. Unplug the refrigerator and look over the ice room temperature sensor wiring at the control board for damage.
Differential
Likely causes of “Kenmore 111 model bottom-freezer refrigerator showing iD Lo or iD Hi”, and how to tell them apart
- 1
Damaged or broken wiring between the ice room temperature sensor and the control board
What separates it iD Lo or iD Hi shows and the refrigerator cannot read the ice room temperature
How to confirm Unplug the refrigerator and look over the ice room temperature sensor wiring at the control board for damage
- 2
A ice room temperature sensor whose circuit resistance is outside the chart's range
What separates it iD keeps returning after the wiring is repaired and the reading is wrong
How to confirm Measure the resistance through the ice room temperature sensor circuit from the control board; the chart wants it between 1,000 and 40,000 ohms
- 3
A connector or splice on the ice room temperature sensor circuit that has worked loose
What separates it The iD display comes and goes when the door is opened or the refrigerator is bumped
How to confirm Wiggle the ice room temperature sensor connector at the control board with the refrigerator unplugged and look for a bent pin
Before you touch a setting
Record this first — changing settings destroys the evidence
- That the display shows iD Lo or iD Hi, the ice room sensor failure
- The resistance through the ice room temperature sensor circuit from the control board
- The condition of the ice room temperature sensor wiring and any broken wires you found

0 of 4 completedCorrect only the documented fault domain
ReversibleUnplug the refrigerator and check the ice room temperature sensor wiring connected to the control board for damage. Repair any broken wires. Measure the resistance through the ice room temperature sensor circuit from the control board. Replace the ice room temperature sensor if resistance isn't between 1,000 and 40,000 ohms. Parts named: ice room temperature sensor.
Unplug the refrigerator and check the ice room temperature sensor wiring
ReversibleThe chart starts iD with the wiring that runs from the ice room temperature sensor to the control board, so look along it for damage before you measure anything.
Repair any broken wires on the ice room temperature sensor circuit
ReversibleA broken wire on the ice room temperature sensor circuit can produce the iD Lo or Hi display by itself, and the chart says to repair it before you replace the sensor.
Measure the resistance through the ice room temperature sensor circuit and replace it if it is out of range
ReversibleMeasure from the control board: the chart says to replace the ice room temperature sensor if the resistance isn't between 1,000 and 40,000 ohms, and to leave it if it is.
Model-specific
What is true of this model and not of its siblings
- Shown as
- iD Lo or iD Hi (111 model bottom-freezer table).
- Part named by the chart
- Ice room temperature sensor.
Stop boundary
When this stops being a self-service repair
- !Unplug the refrigerator before you touch any wiring or part for iD, and plug it back in only after the repair, since the control board stays live while it is plugged in
- !Do not leave the refrigerator running with a wrong ice room reading for long, because the control cannot keep food temperatures right without it

Exact questions
Common questions
What does iD Lo or iD Hi mean on a Kenmore 111 model bottom-freezer refrigerator?+
Kenmore's service table lists this code as: ice room temperature sensor failure.
What should the ice room temperature sensor circuit measure?+
Between 1,000 and 40,000 ohms; the chart replaces the sensor if it does not.
Do iD Lo and iD Hi need different fixes?+
No, the chart gives one procedure for both displays.
Which part does the chart name for iD?+
The ice room temperature sensor.
How is rt different?+
rt is a different sensor with its own row in the same table, though the procedure has the same shape.
